Hello everyone. I am developing my project. I am using checkboxes, combobox and a button. I select an item from combobox let me say it is Prof DR JOHN NHOJ and I am clicking more than one check boxes. For example barcelona, apple, NYC and bus are ticked for Prof DR JOHN NHOJ. I am clicking save button. Until here everything is Ok. However for the second try. I want to disable barcelona apple, NYC and bus checboxes. For example I will chose another person from combobox and I will assign Real Madrid; grapes; RI, train for this person. I don''t want to see barcelona, apple, NYC and bus checkboxes enabled. Is there any solution ?

推荐答案

if(checkboxname.isSelected())
checkboxname.setEnabled(false);

是的.

I did.

是的，可能的.只需从数据源本身中筛选先前已选择的项目.

两种方式:
1.如果要获取每个人的数据，则可以在查询级别进行过滤.
2.如果要一次获取数据并一次又一次地使用，则需要编写自己的逻辑以从完整集中删除已选择的数据.

试试吧！

Yes, possible. Just filter the previous already selected items from the datasource itself.

Two ways:
1. If you are fetching data for every person then you can do the filtration at query level.
2. If you are fetching data once and using again & again, you need to write your own logic for already selected data removal from full set.

Try out!
